CHARLES J'. MARSIIALL, OF BELOII, IVISCONSIN, ASSIGNOR TO P. B. YATESMACHINE COMPANY, OF BELOIT, WISCONSIN, A CORPORATION OF WISCONSIN.

STOCK-FEEDER FOR WOODVORKING-MACI-IIN'ES.

To all whom t may concern Y Be it known that I, CHARLES J. MARSHALL, acitizen of the United States, residing at Beloit, in the county Vof Bockand State yof -Wisconsin, have invented certain new and usefulImprovements in Stock-Feeders for lVoodWOrlringMachineS, of which thefollowing is a specification. Y

The present invention has for its object the provision of a machine forfeeding stock material to wood-working machines of Whatever character,whether planers, matchers or what not.

The invention is especially adapted to the diiiicult field of feedingmill-run material including that which is rough, nonuniform in size andcrooked, or otherwise distorted as to shape as well as to the feeding ofstock material of select quality. i In most mills there is turned out alarge amount of material which by reason of-misshapen character isunsuited for' handling in the ordinary way, and for this reason it isculled out and amounts substantially to waste. Much of such material issound and inherently valuable and could be used in many situations wereit not for the diliculty in handling the same.

Means have'been devised for more or less successfully working cullstock, but it has been diiicult and expensive tol feed such material ina way to present the same to the machine so as to secure good resultstherefrom. f

. it is for `meeting such a situation as this, in addition to thelhandling of standard quality of stock that the present invention hasbeen devised tothe end that mills provided with a machine embodying theinvention shall be enabled to utilize the very largest proportion oftheir sound'material both straight and crooked,- tlius reducing waste toa minimum and securing a product of the greatest uniformity and of thebest quality.

To most efliciently feed and work such mill-run stock it is found thatVit is best presented to the milling or matching machine on edge asdistinguished from its side, and the present machine'is especiallydesigned to handle the stock on edge.

In order that the salient features of thev invention may be most readilyunderstood a preferred embodiment of the same isset forth in theaccompanying drawings and the following detailed description predicatedthereon. The invention being suscep- -tible of. embodiment in variedconstrucward end of the machine upon a somewhatv enlarged scale; Y

Fig. 6 is an enlarged sectional view on the line 6 6 of Fig. 1;

Fig. 7 yis a detail view illustrating the mounting of the forwardingrolls;

Fig. 8 is an enlarged detail section on the line 8 8 of Fig. 2; and

Fig. 9 is a fragmentary rear elevation of the directing and excludingplate.

Having reference to the drawings in detail, the machine frame isillustrated as comprising standards 11 with longitudinal members 12 andcross members 18, said frame having suitably journaled thereinransmission shafts 14, 15, 16, 17, 18 and 19 disposed in substantiallyparallel relation longitudinally of the frame. A drive shaft 20 and adriven shaft 21 are likewise journaled in the machine frame transverselythereof, the drive shaft being driven by means of a pulley 28 from a'suitable source of power, in turn driving the shaft y21 by means of abelt 24 engaging thepulley 25, Vthe belts of the drive and drivenpulleys being maintained taut byV suitably disposed belt tighteners 26and 27.V The transmission shaft 14 is driven from the shaft 21 by meanso f bevel gears 28, 29 and said shaft 14 in turn drives the shaft 16 bya series of sprocket chains 30 traversing a series of sprocket wheels 31on the shaft 14 and corresponding sprocket wheels 32 on the shaft 16.The chains 30 areheld taut by means of gravity tightening rolls 33pivoted at 34 and weighted at 35. It will be observed that the left handreach'of the chains 30 as viewed in Figs. 3 and 4 extends in Vasubstantially vertical direction, the slack of said chains being takenup by the tiglhtening rolls 33 at the right hand side.

aving reference to Fig. 4 ofthefdrawing the shaft 17 is driven fromthe/sprocket 31 by means of the sprocket chain 36 traversing thesprocket 37.V Power is transmitted from the shaft 17 to the shaft V18 bymeans of the pinions 38, 39 and power is transmitted from the shaft 18to the shaft 19 by means of the chain 40 traversingthe sprocket 41 onthe shaft 18 and the sprocket 42 on-the shaft 19. The chain 40 ismaintained 'taut by means of the tightener roll 43 swung from the shaft19 as a pivot and counter-weighted at 44. It will be observed that asviewed in Figs. '3 and 4 the right hand reach of the chain v extends ina substantially vertical right-line inV opposition to the vertical reachof the chain 3() and at but a slight distance therefrom, the slack ofthe chainl 40 being taken up at the left hand side.

Near the forward end ofthe stock feeder and in order to provideclearance for other parts of the machine there disposed the Aprovidedwith Vjam nuts 56 against which shaft 41 terminates, and the shaft 15serves to carry a sprocket 45 traversed by a shorter chain 46 whichengages above one of the sprockets 32 of the shaft 16. The inner reachof this chain extends in the same plane longitudinally viewed as doesthe inf ner reach of the chains30 while the outer reach of the chain 46is -tightened by means .of a roll 47 which is pressed against the chainby means of a spring 48 mounted upon kthe rod 49 pivoted at 50 to thevertical standard 51.

The standard 51 is one of a longitudinal series the upper ends of whichserve as journal mountings 'for the shaft 16 and the lower ends of whichare pivotedupon the shaft 15 and extend for a short distance be- 'lowthe shaft 15 terminating in studs 52 transversely bored. A series ofscrew spindles 53 are adjustably threaded into sleeves 54 pivoted at 55to the machine frame, and

the studs 52 Vof the standards 51 abut to limit the outward swing of thestud` and consequently the inward swing of the upper ends of thestandards and the shaft 16. Upon the screw spindles 53 opposite the jamnuts v56 are disposed'loose collars 57 forming inner abutments forsprings 58 disposed between the collars 57 and jam nuts 59 on the freeends of the screw spindles. l By this arrangement the upper ends of thestandards, theshaft 16, the sprockets 32 and the chains 30 and 46 mayyield outwardly to the right as viewed in Figs. 3 and 4 and awayfrom thechains40 upon the sprockets 41 and 42; all for a purpose whichhereinafter will be made clear.

Transversely journaled in the machine frame forwardly of the drive shaft2O is a countershaft'60'driven by a sprocket 61 `mounted thereon bymeans of a chain 62 traversing a sprocket 63 on the drive shaft Y itsupper end with 4a sphericalstock feeding head 72 having a roughenedsurface formed by meridian ribs 73. V Y

The stock feeding roll 67VV and the stock feedingl head 72 are disposed'in alinement viewed longitudinally of the machine with the right hand orinner faces in the same vertical plane,wh1ch plane corresponds sub-Vstantiallywith the plane of the inner reach of the chains 40, and marksthe left hand boundary of the line of travel of the stock through themachine.

s a companion member to the. feed roll 67 but yieldingly mounted withreference thereto, is a 'feed roll 67EL having a similar roughened face68a carried by a substantiallyvertical shaft 66a. The two shafts 66 and66a have mounted thereon at their lower ends companion pinions V74,74Pby means of which the feed roll 67 a is driven in unison with thefeed roll 67 but in an opposite direction. The bevel pinions 64, 65 andthe pinions 74 7 4L are mounted within a housing' 75, transiixed by apivot 76 engaged by a yoke member 77 carrying Ythe upper journal 78 ofthe shaft 66a, inrorder to permit of the tilting of the shaft 66a Vaboutthe pivot 76 and thus vary the distance between the stock feeding rolls67 and 67 in the manner to be later described. Alongside the shaft 71 ofthe stock feeding head 72 is a companion shaft 71EL and head 7221 drivenin Va similar manner to that of the Ystock feeding rolls, the drivingpinions being contained within the housing 79 and the shaft 71 beingsimilarly pivot-ed at 80 by means of a yoke 81.

. The yielding stock feed roll 67a and the yielding stock feed head 72EL are so mounted as to be manually operable in unison to positivelymove them away from the companion fixed roll and head. and to permit ofindependent yielding, n the mannrnr follow "and 7 it will be observedlthat a hand lever 82 is connected to the rock shaft 83 carrying a rockarm 84 having attached thereto at 85 alink 86 extending across themachine frame and through a coupling member37 to which a yieldingconnection is made lby means of the jam nuts 88, spring 89 and theadjusting nuts 90. The couplingmember 87 is in the arm 91 of a leverfulcrumed at 92, the upper arm 93 of the lever terminating in a Crosshead 9d which connects the ends of two links 95, 96. The link 95provided with the jam nuts 97 which bear upon one'side of a boss 98 ofthe journal boxing 78 of the yielding-stock feed roll 67a while the linkextends through said boss and is encircled by a spring 99confinedbetween said boss and the adjusting'nuts 100.l lThe link 36 is similarlyconnected with the shaft 71a of the stock feeding head 72a.

1n advance of the stock feed rolls and heads a xed guide 101 is disposedwith its inner face in substantially the same longitudinal verticalplane as the inner facesV of theV fixed stock feed roll and stockY feedhead. Opposite the fixed guide 101 is a yielding guide 102 carried bylinks 103 by which a parallel motion is imparted thereto. A hand lever104 is adjustably connected to one of the links 103 by means of asegment slot and set screw 105, in order that by said lever the yieldingguide 102 Ymay be moved toward or away from the fixed guide 101. Theguide 102 is yieldingly pressed toward the fixed guide 101 by means of aspring `106 mounted upon detent 107 connected to the lever at 108, saidspring being disposed between adjusting nuts 109 and a collar 110 whichengages within abifurcated portion 111 of a standard 112. TWhile by thismeans the yielding guide is normally spring-pressed toward the fixedguide, it may be moved away from said guide 'by means of a hand leveragainst the tension of the spring, or it may be quickly released incasel of emergency or for purposes of adjustment by pushing the detentrod 107 to one side so'as to disengage the collar 110 from the notch 111of the standard 112; The extent to which the guide 102 may approach theguide 101 Vis limited by an adjustable stop 113 disposed in the path ofthe lever 104. At the right hand side of the machine viewed as from therear, standards 114 are provided with overhanging arms 115 to facilitatethe delivery of stock to the feeder by the kman in charge. The forwardstandard may eiiiciently'be provided with a spur 116 upon which tofulcrum the timber and prevent its slipping as it is elevated intoplace.. As the strips of material accumulateon the bracket Yarms 115they are 'pushed toward the left until their under-facesl are engaged bythe chains 30 whereupon they are carried to the .left by the chains anddropped into lthe 'and heads and also with the space between the fixedand yielding guides at the forward end of the machine. At the rear endthere is advantageously mounted above therail 117 antifriction rail 118to receive and support the rear end of exceptionally long pieces ofstock delivered into the guide channel.

At a point preferably in advance of the stock feed heads 72, 72a and atthe rear of the stock feed rolls 67, 67u is arranged a defiector plate119 inclined downwardly and to the rear as shown in Figs. land 5 so thatif stock Ais delivered to the machine in advance of its proper positionit` will be deflected backwardly by the plate 119 and its front endpushed back to the rear of the plate'119 and a directing and excludingplate 120 to the upper edge of which the defiector 119 is secured.

As will be seen from Figs. 6 and 9 the rear face of the directing andexcluding .plate 120 is cut away at 121 at a point corresponding tothespace between the stock feed rolls 67 and 67, vthe upper wall of theopening 121 being inclined. downwardly and to the front as indicated at122, in order that any material wider than the height of the opening 121will be excluded and that material sufficiently narrow will be guidedvdownwardly by the inclined lwall 122 to insurecontact between the loweredge of the material and the track 117.

The stock material having vbeen fed into the guide channel between thechains 30 and 10is fed downwardly by said chains until its forward end-is engaged by the spherical stock feeding heads 72, 72a. The axis ofrotation of these heads being inclined to the vertical they tend to feedthe stock both downwardly and forwardly. As soon as the stock contactswith the rail 117 the action kof the stock feeding heads is to hold thestock firmly upon the rail and at the same time toforward it to thestock feeding rolls.

At the left: hand side of the machine viewed from the rear the standards123 which carry the shaft 19 are themselves disposed at one side of theverticalreach of the chain 40 and have adjustably mounted thereon bymeans of the screws 124: guide plates 125v which serve as guidingabutments for the stock incase of excessive warping which would 4pressthe chains out of vertical alinement. v

Upon therupper ends of the standards 123 and longitudinally connectingthe same is a ,deflector rail 126 to prevent a piece of stock materialroughly handled from over-riding the machine and to guide the samebackinto the guide channel.

t might happenr with roughimaterial that boards fed longitudinallythrough the channel between the chains mighthave slivered portions whichwouldV catch onl the chains and under the'forwarding impulse of the feedrolls pull the chains out of their vertical path. To safeguard againstthis,

arms 127 and 128 are provided which receive between themselves theboards fed downwardly bythe chains and present Ysmooth friction surfacesbetween which the boards YVcase the arm 128 will give yand take with thestandard 51. 'Io insure that the material will enter between the arms127 and 128 a deflector blade 129 may additionally be used.

In advance of the stock feeding rolls and :the directing and excludingdevice and in close working ,proximity to theY Xed and V.yielding guidesis advantageously arranged channel, and a directing member at the disahold-down shoe 130 shown as pivoted at 131'andyieldingly forced downupon the material by means of the spring 182 mounted upon the-rod 133lwhich has a fixed mounting atlil. ,This hold-down shoe may Vform a partof the stock feeder or of the `wood-working machine to which the stockis fed. Y Y

VIt will be observed that by the machine hereinbefore described stockmaterialvarying considerably as to thickness and breadth as well aslength, may be fed to anytype of wood-working machine; though suchmaterial may be warped and crooked it will be presented to the feedheads and rolls vand by them between horizontal and vertical guides inproper relation to the machine.
